Overview
The AP64102QSP-13 is a synchronous buck converter from Diodes Incorporated, housed in an SO-EP-8 package. It operates with an input voltage range of 3.8 V to 40 V and delivers up to 1 A output current. The adjustable output voltage spans from 800 mV to 40 V. Key electrical parameters include a quiescent current of 25 uA and a switching frequency adjustable between 100 kHz and 2.2 MHz. The device supports shutdown functionality and functions within a temperature range of -40 C to +125 C.
Feature Summary
- Synchronous buck topology for high efficiency
- Adjustable switching frequency from 100 kHz to 2.2 MHz
- Integrated shutdown control capability
- Wide input voltage tolerance up to 40 V
Applications
- Industrial equipment power distribution
- Consumer electronics voltage regulation
- Embedded system bias supplies
Procurement Notes
Verify the specific suffix '13' indicates tape and reel packaging configuration. Confirm RoHS compliance status through official documentation before integration. Ensure the SO-EP-8 thermal pad soldering process meets manufacturer guidelines for reliable operation under specified thermal conditions.
Selection Notes
Select this component when a single-output synchronous regulator is required with inputs up to 40 V. The wide frequency adjustment allows optimization for EMI or transient response needs. Compare against the AP64100 variant if higher current capacity is necessary, as this model provides 1 A output.
Part Context
This part belongs to the AP64xxx series of high-voltage step-down converters by Diodes Incorporated. These devices are designed for applications requiring robust performance across varying load and line conditions. The series emphasizes compact design with minimal external component count while maintaining stable regulation.
Replacement Considerations
The AP64100QSP-13 is a related variant offering 600 mA output current. Verify pin compatibility and thermal requirements when substituting between these models within the same package family.
